How to deal with #LinkedData for defining good #ActivityPub extensions is something that the dev community struggles with for years and led to endless discussions. Meanwhile in practice most impls follow the "just-JSON" path and throw in some @context just for good measure.
Last weeks these discussions raged on in @fedidevs matrix chatroom.. https://matrix.to/#/#fediverse-developer-network:matrix.org
Maybe spec can be reformulated as following a JSON-first approach with optional additional LinkedData-profile.
